Application filed October 27, 1 9244 Serial- N0. 746,218;

To all whom it may concern:

Be it known that I, MICHAEL B. BULGER, a citizen of the United States, residing at Beaver Dam, in the county of Dodge and State of l Visconsin, have invented a new and useful Dip Tank, of which the following is a specification.

The present invention relates to dip tanks employed for containing enamel in dipping castings or the like, and for the sake of explanation, it might be stated that naphtha is employed as a thinning medium for thinning the enamel, and it is the object of the present invention to provide a dipping tank which will be absolutely fire-proof.

An important object of the invention is to provide a tank of this character wherein drippings from dipped castings may drain back to the dipping tank.

Another object of the invention is to provide means for automatically closing the dipping tank should the contents of the dipping tank become ignited.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and, claimed, is being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a side elevational view of a dipping tank constructed in accordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is an end elevational View.

Figure 4 is an elevational view of the supporting legs for the drip tables.

Referring to the drawings in detail, the reference character 5 indicates the tank that contains the liquid enamel in which the castthe coiled spring being secured to the upper end of the arm carried by the tank 5 so that when the closure 6 is in its open position, the spring will be under tension.

The drip table includes a pair of members l1 pivotally mounted at the upper ends of the leg members 12, the leg members embodying upper sections 13 and lower sec tion 14. Openings are formed in the sections 13 and 1a and accommodate pins 15 for holding the table at various heights with respect to the tank 5 to insure a proper draining of the enamel to the tank 5.

Flanges 16 are provided at the forward ends of the members 11 and are designed to direct the liquid enamel into the tank 5.

As illustrated by Figure 1, the cover 6 normally engages under the member 11 supported directly thereabove, so that the member 11 will act normally to hold the closure in its inactive or open position.

A bar indicated at 17 is carried by one of the members 11 and engages the opposite member 11 for holding the drain table in its active position. The rod 18 is carried by one of the members 11 and has connection with the latch member 19 by means of the fusible link 20 to the end that should the liquid within the tank 5 become ignited, the heat will cause the destruction of the fusible link 20, releasing the members 11.

l/Veights 21 are carried by the members 11 at points adjacent to the outer ends thereof, so that when the fusible link is destroyed the weights will cause the members 11 to take positions as shown in dotted lines in Figure 1, releasing the closure 6 and allowing the spring to close the tank 5 to smother the fire therein.

I claim p 1. In a device of the character described, a tank, a closure for the tank,,a sectional drip table mounted above the tank, a securing means including a fusible link for holding the drip table in its active position, a spring for normally urging the closure to its closed position, and said fusible link adapted to be destroyed by fire to release the drip table and allow the closure to move to its active position.

2. In a device of the character described, a tank, a spring actuated closure forming a part of the tank, a drip table supported adjacent to the tank for delivering material to the tank, said closure adapted to engage the drip table, to hold the closure in its open position, and means for moving the closure to its closed position When the drip table moves to its inactive position.

3.1m a device of the character described, a tank, a drip table adapted to feed material to the tank, a spring-pressed hinged closure for the tank, said closure adapted to be normally held in its inactive position by its contact with the drip table, aesecuring mern 10 her including a fusible link for normally holding the drip table in its active position, and sald drip table adapted to be released When the fusible link is destroyed, and a spring for moving the closure to a closing position. i

In testimony that I claim the foregoingas my own, I have hereto afiixed my signature.

MICHAEL B. BULGER.
